1.2 User and Product Safety
Never use strong pressure on the screen or subject it to severe impact, as the LCD
panel can crack and possibly cause personal injury. If the LCD panel is broken,
never touch the liquid inside, for such contact can irritate the skin.
Although the PT-90 mobile computer meets IP65 standards for water and dust
resistance, avoid prolonged exposure to rain or other concentrated moisture.
Conditions exceeding IP65 standards could result in water or other contaminants
entering the PT-90.
Use only the approved AC Adapter with the PT-90. Use of an unapproved AC
Adapter could result in electrical problems, or even cause a fire or an electrical
shock to the user.
Be sure that only authorized suppliers are allowed to disassemble and reassemble the
device. If the device or parts are damaged due to wrong handling, the product and
parts warranty is void.
Always make back-up copies of all important data. This is easily done using a cable
or single cradle (optional) to transfer data to the computer. The manufacturer is not
liable for any data damage or data loss caused by deletion or corruption while using
this device, or due to a drained battery.
Lithium-ion battery packs may get hot, explode, ignite and/or cause serious injury if
abused. Please follow the safety warnings listed below.
Warnings:
Do not place the battery pack in fire or heat the battery.
Do not install the battery pack backwards so the polarity is reversed.
Do not carry or store battery pack together with metal objects.
Do not pierce the battery pack with nails, strike the battery pack with a
hammer, step on the battery pack or otherwise subject it to strong impacts or
shocks.
Do not solder directly onto the battery pack.
Do not expose battery pack to liquid, or allow the battery contacts to get
wet.
Do not disassemble or modify the battery pack. The battery pack contains
safety and protection devices, which, if damaged, may cause the battery
pack to generate heat, explode or ignite.
Do not discharge the battery pack using any device except for the specified
device. When it is used in devices other than the specified devices, the
battery pack can be damaged or its life expectancy reduced. If the device
causes any abnormal current to flow, it may cause the battery pack to
become hot, explode or ignite and cause serious injury.
In the event the battery pack leaks and fluid gets into the eyes, do not rub the
eyes. Rinse well with water and immediately seek medical care. If left
untreated, the battery fluid could cause eye damage.
